What did Hernando de Soto do in Oklahoma?

Hernando de Soto, the Spanish explorer, is known for his expedition through the southeastern United States in the 1540s, but he did not specifically explore Oklahoma. His journey took him through regions that are now part of Florida, Georgia, Alabama, Mississippi, and Arkansas. While he did not directly interact with Oklahoma, his expeditions contributed to European knowledge of the interior of North America and set the stage for future exploration and colonization in the region.
